Primary vaccination with the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) in infants in Mali and Nigeria: a randomized controlled trial

BackgroundPneumonia is still the leading cause of death among children in Africa, and pneumococcal serotypes 1 and 5 are frequently isolated from African children with invasive pneumococcal disease below the age of 5 years. The immunogenicity, safety and reactogenicity of 3-dose primary vaccination with the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) were evaluated in infants in Mali and Nigeria.MethodsIn an open, randomized, controlled study, 357 infants received DTPw-HBV/Hib and OPV primary vaccination with (PHiD-CV group) or without (control group) PHiD-CV co-administration at 6, 10 and 14 weeks of age. Pneumococcal antibody responses and opsonophagocytic activity (OPA) were measured and adverse events (AEs) recorded.ResultsOne month post-dose 3, ≥ 97.2% of PHiD-CV-vaccinated infants had an antibody concentration ≥ 0.2 μg/mL for each vaccine pneumococcal serotype except for 6B (82.0%) and 23F (87.6%) versus < 10% in the control group except for serotypes 14 (35.7%) and 19F (22.5%). For each vaccine serotype, ≥ 93.3% of PHiD-CV recipients had an OPA titre ≥ 8, except for serotypes 1 (87.6%) and 6B (85.4%), compared to < 10% in the control group, except for serotypes 7F (42.9%), 9V (24.1%) and 14 (24.5%). Anti-protein D geometric mean antibody concentrations were 3791.8 and 85.4 EL.U/mL in the PHiD-CV and control groups, respectively. Overall incidences of solicited and unsolicited AEs were similar between groups.ConclusionsIn sub-Saharan African infants, PHiD-CV was immunogenic for all vaccine pneumococcal serotypes and protein D. Vaccine tolerability was generally comparable between the PHiD-CV and control groups.Trial RegistrationClinicalTrials.gov identifier: NCT00678301.

Awareness and uptake of the Pap smear among market women in Lagos, Nigeria

Our study evaluates the effect of an educational programme on awareness and uptake of the cervical cancer screening test (Pap smear) by women in a model market in Lagos, Nigeria. This was a quasi-experimental study using a multistage sampling technique. A total of 350 women were divided into two groups. A baseline survey on awareness of the Pap test and screening practices was carried out using pre-tested, interviewer administered, structured questionnaires. Participants in the intervention group received sessions of community based health information on cervical cancer screening tests while participants in the control group received health information on hypertension. Subsequently, participants in both groups were reassessed to evaluate the effect of the educational programme on the Pap test and cervical screening uptake. Data were analysed with the Epi-info version 6.04. Awareness about the Pap test was low at baseline; only 6.9% and 12.0% of participants in the intervention and control groups, respectively, had heard of Pap smears. Furthermore, less than 10% had correct information on the use of the Pap test. Post-intervention, there was a significant and proportional increase in the knowledge of the Pap test in the intervention group (P<0.05). However, uptake of the test was quite low in the intervention and control groups both pre- and post-intervention and there was no significant change in uptake. We concluded that essential schemes are required to enhance access to screening, as knowledge alone is insufficient to promote acceptance and use of cervical cytological screening tests.

Safety and immunogenicity of 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) in Nigerian children: Booster dose and 2-dose catch-up regimens in the second year of life.

In a previous study, 3-dose primary vaccination of Nigerian infants with the 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) was immunogenic for vaccine pneumococcal serotypes, with comparable tolerability between PHiD-CV and control groups. In an open-label study (ClinicalTrials.gov, NCT01153893), 68 primed children received a PHiD-CV booster dose co-administered with a diphtheria-tetanus-acellular pertussis (DTPa) booster dose at 15–21 months and 36 children unprimed for pneumococcal vaccination received two PHiD-CV catch-up doses (first dose co-administered with DTPa booster dose) at 15–21 and 17–23 months. Adverse events were recorded and immune responses were measured before and one month after vaccination. In both groups, pain was the most frequent solicited local symptom and fever was the most frequent solicited general symptom after the booster dose and each catch-up dose. Few grade 3 solicited symptoms and no vaccine-related serious adverse events were reported. After booster vaccination, for each vaccine serotype, at least 98.5% of children had an antibody concentration ≥0.2 µg/ml and at least 94.0% had an opsonophagocytic activity (OPA) titer ≥8. After 2-dose catch-up, for each vaccine serotype, at least 97.1% had an antibody concentration ≥0.2 µg/ml, except for serotypes 6B (82.9%) and 23F (88.6%), and at least 91.4% had an OPA titer ≥8, except for serotypes 6B (77.4%) and 19F (85.3%). PHiD-CV induced antibody responses against protein D in both groups. In conclusion, PHiD-CV administered to Nigerian toddlers as a booster dose or 2-dose catch-up was well tolerated and immunogenic for vaccine pneumococcal serotypes and protein D.

Factors influencing quality of life and predictors of low quality of life scores in patients on treatment for pulmonary tuberculosis: a cross sectional study.

There is paucity of information on the quality of life of patients with pulmonary tuberculosis in Nigeria. This study assessed the factors influencing their quality of life and the independent predictors of low quality of life scores. Two hundred and sixty consecutive patients with pulmonary tuberculosis seen at the Lagos University Teaching Hospital were evaluated for health related quality of life using the World Health Organization Quality of life instrument (WHOQoL-BREF). Sociodemographic characteristics of the patients were related to the various domains of quality of life and a multivariate logistic regression analysis was performed to identify the independent predictors of low quality of life scores in the patients. The mean age of the patients was 36.7±12 years. Sex, age and marital status of patients were found to influence quality of life scores. The independent predictors of low quality of life scores were low monthly income, duration of the illness, concomitant illnesses, unemployment, advancing age and male gender. Several socio demographic and economic factors influenced the quality of life of patients with tuberculosis and are predictive of poor scores. It is important to consider these factors when treating patients with tuberculosis to optimise outcome of care.

Youth friendly health services in a rural community of Lagos, Nigeria: are the youths receptive?

Abstract Background: Globally, the youths constitute a major segment of most societies particularly in developing countries. This study was undertaken to assess the perception and practices related to youth friendly health services (YFHS) by in-school adolescents in a rural community of Lagos, Nigeria. Methods: A descriptive cross-sectional survey was conducted on 400 proportionately selected consenting respondents from the senior classes of the three secondary schools in Agbowa community. A pre-tested interviewer-administered questionnaire was used for data collection and analysis was done with the aid of statistical software. Results: Most of the respondents were in the age range of 12–15 years with mean age being 15.33±1.54 years. About half (46.8%) of the respondents correctly described adolescents as persons between the ages of 10 and 19 years. The majority (83.2%) of the respondents first heard about the Youth Friendly Health facilities from parents, guardians and friends. However, only few of the respondents had ever visited a Youth Friendly Center. A good location, convenient hours and comfortable surroundings were the most appealing aspects of YFHS. The provision of a seminar room and educational materials (60.8% and 70.8%, respectively) are important to the respondents. Reproductive health (56.8%) was the most preferred health education topic chosen by the respondents. Conclusion: Sensitization of the youths in the Agbowa community about youth friendly health services and provision of such services would be useful in reducing risky practices and improving their health.

Factors affecting utilization of youth friendly health services in Lagos State, Nigeria

Abstract Background Youth friendly health services (YFHS) are services that attract, respond to the needs of and retain young people for continuing care. This study was conducted to determine the factors affecting utilization of government (GYFF) and non-governmental youth friendly facilities (NGYFF) in Lagos state, Nigeria. Methods A descriptive cross-sectional study was conducted. A total of 543 adolescents aged 15–24 years, between August 1, 2014 and October 31, 2014 were consecutively recruited from 10 (five government and five non-governmental) youth friendly health facilities that had been in operation for at least 6 months prior to the study. Logistic regression was used to determine predictors of utilization of youth friendly health facilities. Results Overall, the mean age of respondents was 17.9 ± 2.8. However, the mean age of respondents at GYFF (18.5 ± 3.0) was significantly higher than those at NGYFF (17.1 ± 2.5) (p < 0.001). Of the 567 youths enrolled, 196 (34.6%) had good utilization of youth friendly facilities (YFF) (34% from the GYFF and 35.2% from the NGYFF). Marital status, school attendance, having a baby, satisfaction with visit, perception that information shared was kept confidential and accessibility of the youth friendly services were associated with utilization of YFF (p < 0.05). Confidentiality and access to facilities were predictors of utilization of YFF. Conclusion There is poor utilization of both government and non-governmental youth friendly services in Lagos, Nigeria. There is a need for both the government and private sector to harmonize resources aimed at encouraging utilization of YFF in Lagos, Nigeria.

Causative factors for sexual and reproductive health status of pregnant adolescent girls in urban communities of Lagos, Nigeria

Abstract Background The overall goal of this study was to determine the causative factors for pregnancy status in adolescent girls in two communities in the Lagos Island local government area. Methods A mixed methods (quantitative and qualitative) study reviewing routine health facility antenatal care (ANC) records and conducting focus group discussions among 46 pregnant adolescents, exploring their views about sex, contraception, pregnancy and sexual and reproductive health (SRH) services, was carried out. Key informant interviews were also carried out among healthcare workers and community members to assess their perceptions of adolescents’ SRH problems. Results Five percent of those accessing ANC services were adolescents. Pregnant adolescents were found to access health services at later stages of their pregnancies due to the shame and stigma associated with their condition. The presence of morbidity in the form of anaemia (33%) and HIV (2.4%) was also found in this population. Social factors such as peer pressure and the desire to develop or maintain a relationship were found to be the major reasons for initiation of sexual activity by the adolescents. There was generally poor knowledge and utilisation of contraceptives, leading to unprotected sex and, thus, unintended pregnancies. Conclusion SRH information and services should be made readily available to adolescents at all levels of care.

Perception and practices of Lagos state residents on the prevention and control of malaria in Lagos, Nigeria

Background: Malaria remains one of the major public health problems worldwide. It is an important cause of death and illness in children and adults in sub-Saharan Africa accounting for over a million deaths per year. The purpose of this study was to determine the perception and practices of the Lagos state residents on malaria. Materials and Methods: A descriptive cross-sectional study was conducted in five of the 20 local government areas (LGAs) in Lagos Nigeria. Using a multistaged sampling method, 5 LGAs and 12, 500 study participants were selected. The survey instrument was a structured, pretested, interviewer-administered questionnaire which sought for information on knowledge, attitude, and practices of the respondents on malaria. Data analysis was done using Epi-info V6.04d software. Results: The mean age was 35.5 ± 10.5 years. There were 8697 females (69.7%) and 3786 (30.3%) males. About 84% of the respondents correctly knew that malaria is transmitted by mosquitoes. Headache was the most recognized symptom (56.6%), while vomiting was the least (17.9%). About half of the participants recognized cleaning the environment as a primary preventive measure and the same number claimed to do so. Approximately, half of respondents claimed usage of insecticide-treated bed nets. Sulphadoxime-pyrimethamine (Fansidar) was the most frequently used (32.7%) antimalarial agent and the use of artemisinin combination therapy was low. Conclusion: Knowledge of malaria symptoms was average and the use of preventive measures was suboptimal. Increasing awareness of all stakeholders on traditional and contemporary preventive measures may enhance the control of this health condition.
